Trade Frederick 210 gold and Replaceable Parts for Constitution. I'm trying to save our gold for other purposes. I see no need for Theology or Music at this point. We can probably research either of those quickly if we need it.
We have a few Christian, Jewish, and Hindu monasteries. So Sci Method wouldn't be all bad. I don't see the need for a bunch more monasteries. I'd like a few more Jewish ones, simply for the hammer and research benefits, but I'm not sure it's worth it. Military Science and 295 gold pries Sci Method loose from Pacal. That's easy because MS doesn't help him with other things but SM moves us forward to other important techs.
I burn another few hundred gold rushing various buildings. Mostly granaries and Djenne's marketplace a little bit on jewish monasteries I'm not sure if they'll finish or if SM will obsolete them before they finish. No need not to experiment a bit.
On the plus side, we have six sources of oil, including directly under St. Louis. So that's one worry eliminated.
(1)Rifling and 400 gold gets Democracy from Frederick. Then we revolt to Emancipation, so we don't have to have a turn of anarchy for it. Research-wise, we move on to Railroad, primarily because it leads to Combustion, which should be our target, because transports and destroyers will be huge for our cross-ocean invasion.
(2)Workers move. Philly gets a library (ridiculously late for such a high commerce city). I am also working on making sure every city has a warm body defending it. Cities get unhappy when they don't have a defensive unit in them, but anything counts a chariot, a horseman, an old warrior, or a rifleman. They don't care and we don't really either, except cities on the coast should probably have a solid defender. Important coastal cities really need the best defenders.
Rest of the time is spent finishing railroad as a tech, building us some machine guns (to spearhead our invasion), working on railing mines and mills (to get the extra hammer), and working on combustion. I am also scouting out Mehmed a bit with a privateer and working on getting some spies to New York to ship over to the other island, probably to check out Pacal.
Military is on its way to Seattle, which will build the big part of our navy, starting next turn, I hope. We'll need transports and destroyers. Destroyers will be critical for protection of our ships. Our galleons can't keep up, but they transport OK.
After Combustion, we need to decide on a tech path. I'd go Corporation to Assembly Line myself. But Biology and Physics have their benefits, too.
We also got a Great Prophet. We could build the temple for Christianity. Or discover Theology. Or join him to a town. None of them seem particularly appealing to me.
No pics, sorry. Pretty straight-forward set of preparation turns.
